Description
Die Erfindung bezieht sich auf eine Lüftungsanlage für einen Innenraum eines Kraftfahrzeuges mit einer Umluftklappe zur Umschaltung zwischen einem Umluftbetrieb und einem Frischluftbetrieb und mit einem mittels eines Rechners drehzahlgeregelten Lüfter, der im Umluftbetrieb eine geringere Luftmenge als im Frischluftbetrieb fördert. The invention relates to a Ventilation system for an interior of a motor vehicle with a Recirculation flap for switching between recirculation mode and a fresh air operation and with one by means of a Computer speed-controlled fan, which in recirculation mode promotes a smaller amount of air than in fresh air mode.
Aus der Praxis ist eine Lüftungsanlage für einen Innenraum eines Kraftfahrzeuges bekannt, deren Umluftklappe in einen Umluftbetrieb oder einen Frischluftbetrieb verschwenkt werden kann. Da der Lüfter in beiden Betriebsarten die gleiche Geschwindigkeit aufweist, bringt das Umschalten zwischen dem Umluftbetrieb und dem Frischluftbetrieb ein an- und abschwellendes Geräusch mit sich, da die von dem Lüfter im Umluftbetrieb zu fördernde Luftmenge geringer als die im Frischluftbetrieb ist. Dieses an- und abschwellende Geräusch wird von dem Benutzer des Kraftfahrzeuges oftmals störend wahrgenommen und trägt zu einer Erhöhung des Geräuschpegels im Innenraum des Kraftfahrzeuges bei. In practice, a ventilation system for an interior of a motor vehicle known, the Recirculation damper in a recirculation mode or Fresh air operation can be pivoted. Because the fan in both Operating modes has the same speed, brings the switching between the recirculation mode and the Fresh air operation with a rising and falling noise itself because the fan to be promoted in recirculation mode Air volume is less than that in fresh air mode. This swelling and decongesting noise is from the user of the motor vehicle is often perceived as disruptive and contributes to an increase in the noise level in the interior of the motor vehicle at.
Es ist Aufgabe der Erfindung, eine Lüftungsanlage der eingangs genannten Art zu schaffen, die eine geräuscharme Umschaltung zwischen einem Umluftbetrieb und einem Frischluftbetrieb gewährleistet. It is an object of the invention To create ventilation system of the type mentioned, the one quiet switching between air recirculation and guaranteed a fresh air operation.
Erfindungsgemäß wird die Aufgabe dadurch
gelöst, dass der Rechner die Drehzahl des Lüfters während
des oder unmittelbar vor dem Umschalten der Umluftklappe
- - aus dem Umluftbetrieb in den Frischluftbetrieb erhöht und
- - aus dem Frischluftbetrieb in den Umluftbetrieb absenkt.
- - increased from recirculation mode to fresh air mode and
- - Reduced from fresh air mode to recirculated air mode.
Aufgrund der Anpassung der Geschwindigkeit des Lüfters während des oder unmittelbar vor dem Umschalten der Umluftklappe wird ein an- und abschwellendes Geräusch beim Wechsel zwischen dem Umluftbetrieb und dem Frischluftbetrieb verhindert. Die Regelung der Drehzahl des Lüfters ist mit der Regelung der Umluftklappe gekoppelt, so dass der Benutzer des Kraftfahrzeuges akustisch ein gleichbleibendes Geräusch wahrnimmt. Due to the adjustment of the speed of the Fans during or immediately before switching the air recirculation flap makes a swelling and swelling noise when changing between the recirculation mode and the Fresh air operation prevented. The regulation of the speed of the Fan is coupled with the regulation of the air recirculation flap, so that the user of the motor vehicle acoustically perceives constant noise.
Bevorzugt passt der Rechner die Drehzahl des Lüfters nach dem Umschalten der Umluftklappe an eine eingestellte Solldrehzahl an. Die Solldrehzahl kann beispielsweise über die Einstellungen einer der Lüftungsanlage zugeordneten Klimaanlage vorgegeben werden, damit sich eine bestimmte Temperatur im Innenraum des Kraftfahrzeuges einstellt, oder von einem Benutzer manuell eingestellt werden. Aufgrund der rechnergesteuerten Anpassung der Drehzahl des Lüfters nach dem Umschalten der Umluftklappe wird der vor dem Umschalten der Umluftklappe herrschende Zustand ohne das Zutun des Benutzers wieder hergestellt. The computer preferably adjusts the speed of the Fan after switching the air recirculation flap to one set target speed. The target speed can for example via the settings of one of the Ventilation system associated air conditioning system are specified so a certain temperature inside the Motor vehicle sets, or manually by a user can be set. Because of the computer controlled Adjustment of the fan speed after switching the Air recirculation flap is the one before switching the air recirculation flap prevailing condition without user intervention again manufactured.
Vorzugsweise verändert der Rechner die Drehzahl des Lüfters kontinuierlich. Mit der kontinuierlichen Veränderung der Drehzahl geht eine relativ geringe akustische Belastung des Benutzers einher. The computer preferably changes the speed of the fan continuously. With the continuous Changing the speed is a relatively small one acoustic load on the user.
Zweckmäßigerweise schaltet die Umluftklappe tastengesteuert in den Umluftbetrieb oder den Frischluftbetrieb um. Der Benutzer des Kraftfahrzeuges kann somit dem Betriebszustand selbst bestimmen, wobei der entsprechende Schalter selbstverständlich mit dem Rechner gekoppelt ist. Alternativ dazu schaltet vorteilhafterweise die Umluftklappe durch Signale eines Luftqualitätssensors in den Umluftbetrieb oder den Frischluftbetrieb um. The recirculation flap expediently switches button-controlled in recirculation mode or Fresh air operation around. The user of the motor vehicle can thus determine the operating state yourself, the appropriate switches of course with the computer is coupled. Alternatively, the switches advantageously Air recirculation damper through signals from an air quality sensor in the recirculation mode or the fresh air mode.
Es versteht sich, dass die vorstehend genannten und nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen. It is understood that the above and not only features to be explained below in the specified combination, but also in other combinations can be used without the frame to leave the present invention.
Die Erfindung wird im folgenden anhand eines Ausführungsbeispieles unter Bezugnahme auf die zugehörige Zeichnung näher erläutert. Die einzige Figur zeigt eine schematische Darstellung einer erfindungsgemäßen Lüftungsanlage. The invention is based on a Embodiment with reference to the associated Drawing explained in more detail. The only figure shows one schematic representation of an inventive Ventilation system.
Eine Lüftungsanlage für den Innenraum eines Kraftfahrzeuges umfasst eine mittels eines Stellantriebes 1 verschwenkbare Umluftklappe 2 sowie einen Lüfter 3, der über einen Motor 4 angetrieben wird. Der Stellantrieb 1 der Umluftklappe 2 und der Motor 4 des Lüfters 3 sind mit einem Rechner 5 gekoppelt, der wiederum mit einem Luftqualitätssensor 6 in Verbindung steht. A ventilation system for the interior of a motor vehicle comprises a recirculating air flap 2 which can be pivoted by means of an actuator 1 and a fan 3 which is driven by a motor 4 . The actuator 1 of the air recirculation flap 2 and the motor 4 of the fan 3 are coupled to a computer 5 , which in turn is connected to an air quality sensor 6 .
Befindet sich die Umluftklappe 2 in einer
Stellung für den Frischluftbetrieb und der
Luftqualitätssensor 6 stellt eine Belastung der Luft mit Abgasen fest,
ergeht ein entsprechendes Signal des Luftqualitätssensors
6 an den Rechner 5, der den Stellantrieb 1 der
Umluftklappe 2 ansteuert, damit diese in die Stellung für den
Umluftbetrieb verschwenkt. Gleichzeitig steuert der
Rechner 5 den Lüfter 3 bzw. dessen Motor 4 an und reduziert
die Drehzahl des Lüfters 3 kontinuierlich, bis eine
bestimmte Luftmenge durch die Umluftklappe 2 gefördert
wird, die beim Verschwenken derselben kein auf- und
abschwellendes Geräusch verursacht. Anschließend bringt der
Rechner 5 den Lüfter 3 wieder auf die Solldrehzahl, die
er vor der Anpassung seiner Drehzahl inne hatte. Im
Frischluftbetrieb ist die vom Lüfter 3 geförderte
Luftmenge größer als die Luftmenge im Umluftbetrieb. Daher
erhöht der Rechner 5 die Drehzahl des Lüfters 3 beim
Umschalten vom Frischluftbetrieb in den Umluftbetrieb, um
ein durch das Umschalten der Umluftklappe 2 verursachtes
auf- und abschwellendes Luftgeräusch zu verhindern.

If the air recirculation flap 2 is in a position for fresh air operation and the air quality sensor 6 detects that the air is contaminated with exhaust gases, a corresponding signal from the air quality sensor 6 is sent to the computer 5 , which controls the actuator 1 of the air recirculation flap 2 so that it moves into the position pivoted for recirculation mode. At the same time, the computer 5 controls the fan 3 or its motor 4 and continuously reduces the speed of the fan 3 until a certain amount of air is conveyed through the recirculation flap 2 , which causes no swelling and swelling noise when it is pivoted. Subsequently, the computer 5 brings the fan 3 back to the target speed that it was at before the speed was adjusted. In fresh air mode, the air volume conveyed by fan 3 is greater than the air volume in recirculation mode. Therefore, the computer 5 increases the speed of the fan 3 when switching from fresh air mode to recirculating air mode, in order to prevent rising and falling air noise caused by the switching of the recirculating air flap 2 .
